Scalable modular LED light fixture with interchangeable mounts

1. A system for preparing scalable, variable-mounting LED lighting fixtures, the system comprising:

at least one front end cap;

at least first and second rails;

at least one LED light module;

at least one housing cover; and,

a set of back ends, each said back end of said set of back ends being differently configured for different mountings,

wherein, depending on a selected number of said LED light modules, a length of each of said first rail, said second rail and said housing cover is adjusted, and

wherein, said length-adjusted front rail, said length-adjusted second rail and said length-adjusted housing cover are disposed to extend between said front end cap and a selected one of said back ends from said set of back ends so as to define a volume for accommodating said selected number of said LED light modules.

2. A system as in claim 1 , wherein said first and second rails are spaced-apart and generally parallel.

3. A system as in claim 1 , wherein said first rail has a constant cross-section along the length thereof.

4. A system as in claim 3 , wherein said second rail has a constant cross-section along the length thereof.

5. A system as in claim 1 , wherein each said LED light module includes a base and a plurality of LED light elements fixed thereto.

6. A system as in claim 1 , further comprising a heat dissipation element located between said selected number of said LED light modules and said length-adjusted housing cover.

7. A system as in claim 6 , wherein said heat dissipation element includes a plurality of spaced-apart fins.

8. A system as in claim 6 , wherein said heat dissipation element is formed integrally with said first rail and with said second rail.

9. A system as in claim 1 , wherein said different mountings include trunnion mounting, tennon mounting, slip fitter mounting, rigid surface mounting, adjustable surface mounting, pole mounting, wall mounting, and canopy mounting.

10. A system as in claim 1 , wherein each said back end of said set of back ends includes a similarly-configured rear end cap.

11. A system for preparing scalable, variable-mounting LED lighting fixtures, the system comprising:

at least one front end cap;

at least first and second rails;

at least one LED light module;

at least one housing cover;

a first back end with a trunnion mounting element;

a second back end with a tennon mounting element;

a third back end with a slip fitter mounting element; and

a fourth back end with a surface mounting element,

wherein, depending on a selected number of said LED light modules, a length of each of said first rail, said second rail and said housing cover is adjusted, and

wherein, said length-adjusted first rail, said length-adjusted second rail and said length-adjusted housing cover are disposed to extend between said front end cap and a selected one of said first back end, said second back end, said third back end, and said fourth back end, so as to define a volume for accommodating said selected number of said LED light modules.

12. A system for preparing scalable, variable-mounting lighting fixtures, the system comprising:

at least one front end cap;

at least first and second rails of different lengths;

at least one LED light module;

at least one housing cover; and,

a set of back ends, each said back end of said set being differently configured for different mountings,

wherein, depending of a selected number of said LED light modules, selecting one of said first rails and one of said second rails; and

wherein, said selected front rail, said selected second rail and said selected housing cover are disposed to extend between said front end cap and a selected one of said back ends so as to define a volume for accommodating said selected number of said LED light modules.
